Based upon our proprietary protocols, these cells are cultured and expanded—and examined to make sure they fulfill the very best expectations for purity, potency, and viability. These cells exhibit:
Bradykinin, potassium, and acetylcholine instantly activate nociceptors. Prostaglandins do not directly activate nociceptors but are very productive in sensitizing them to even further activation by other chemical compounds [twelve].
